Tiger Woods blames prescription drugs for his drunken driving arrest and details from the police report indicate the golfing legend had not been drinking.

Police found Woods asleep at the wheel of his running car on the side of a Jupiter, Florida, road early Monday. He is describing him as confused but cooperative in the police report. He failed several sobriety coordination tests, but passed when he blew into a breathalyzer, the report said.

Woods claimed in a written statement that he suffered “an unexpected reaction to prescribed medications.”

“I didn’t realize the mix of medications had affected me so strongly. I would like to apologize with all my heart to my family, friends and the fans. I expect more from myself too. I will do everything in my power to ensure this never happens again. I fully cooperated with law enforcement, and I would like to personally thank the representatives of the Jupiter Police Department and the Palm Beach County Sheriff’s office for their professionalism.”
